У меня есть эта ошибка в PHP где по приведенным ниже переменным я получаю эту ошибку неопределенные переменные
Notice: Undefined variable: item_id in C:\xampp\htdocs\sites\admin_panel\student_center_system\controller\admin\editmaster.php on line 100 readonly> Notice: Undefined variable: item_name in C:\xampp\htdocs\sites\admin_panel\student_center_system\controller\admin\editmaster.php on line 101 > Notice: Undefined variable: description in C:\xampp\htdocs\sites\admin_panel\student_center_system\controller\admin\editmaster.php on line 102 > Notice: Undefined variable: item_category in C:\xampp\htdocs\sites\admin_panel\student_center_system\controller\admin\editmaster.php on line 103 > Notice: Undefined variable: pic in C:\xampp\htdocs\sites\admin_panel\student_center_system\controller\admin\editmaster.php on line 104 >
это viewitems.php
<?php include "navigation.php"; include "header.php"; include "footer.php"; ?> <?php include("../dbConfig.php"); $query = "SELECT item_id,item_name,description,item_category,pic FROM lost_items_table"; $returnD = mysql_query($query); $returnD1 = mysql_query($query); $result = mysql_fetch_assoc($returnD); ?> <!-- Page Content --> <div id="page-wrapper"> <div class="container-fluid"> <div class="row"> <div class="col-lg-12"> <h1 class="page-header">View Items</h1> <div class="row"> <div class="col-lg-12"> <div class="panel panel-default"> <div class="panel-heading">View Items</div> <table width="100%" class="table table-striped table-bordered table-hover" id="dataTables-example"> <tr> <th>Item Id</th> <th>Item Name</th> <th>Description</th> <th>Item category</th> <th>Picture</th> <th>Edit</th> <th>Delete</th> </tr> <?php while($result1 = mysql_fetch_assoc($returnD1)){ ?> <tr> <td> <a href="adminPage.php?activity=itemdetails&item_name=<?php echo $result1['item_name']; ?>"> <?php echo $result1['item_id']; ?> </a> </td> <td><?php echo ucfirst($result1['item_name']); ?></td> <td><?php echo ucfirst($result1['description']); ?></td> <td><?php echo ucfirst($result1['item_category']); ?></td> <td><?php echo ucfirst($result1['pic']); ?></td> <td> <a href="editmaster.php?item_id=<?php echo $row["item_id"]; ?>">Edit</a> </td> <td> <a href="adminPage.php?activity=deleteitem&item_name=<?php echo $result1['item_name']; ?>">Delete</a> </td> </tr> <?php } ?> </table> <!-- /.table-responsive --> </div> </div> <!-- /.panel --> </div> <!-- /.col-lg-12 --> </div> </div> <!-- /.col-lg-12 --> </div> <!-- /.row --> </div> <!-- /.container-fluid --> </div> <!-- /#page-wrapper -->
Что я уже пробовал:
это мое editmaster.php
<?php session_start(); include("../dbConfig.php"); include "navigation.php"; include "header.php"; include "footer.php"; { } if (isset($_POST['updateitem'])) { if (is_numeric($_POST['item_id'])) { $item_id = $_POST['item_id']; $item_name = mysql_real_escape_string(htmlspecialchars($_POST['item_name'])); $description = mysql_real_escape_string(htmlspecialchars($_POST['description'])); $item_category = mysql_real_escape_string(htmlspecialchars($_POST['item_category'])); $pic = mysql_real_escape_string(htmlspecialchars($_POST['pic'])); if ($item_name == '' || $description == '' || $item_category == '' || $pic == '') { $error = 'ERROR: Please fill in all required fields!'; valid($item_id, $item_name, $description, $item_category, $pic, $error); } else { mysql_query("UPDATE lost_items_table SET item_name = '$item_name', description = '$description', item_category = '$item_category', pic = '$pic' WHERE item_id = '$item_id'") or die(mysql_error()); header("Location: viewitems.php"); } } else { echo 'Error!'; } } else { if (isset($_GET['item_id']) && is_numeric($_GET['item_id']) && $_GET['item_id'] > 0) { $item_id = $_GET['item_id']; $result = mysql_query("SELECT * FROM lost_items_table WHERE item_id=$item_id") or die(mysql_error()); $row = mysql_fetch_array($result); if($row) { $item_name = $row['item_name']; $description = $row['description']; $item_category = $row['item_category']; $pic = $row['pic']; valid($item_id, $item_name, $description, $item_category, $pic,''); } else { echo "No results!"; } } else { echo 'Error!'; } } ?> <!-- Page Content --> <div id="page-wrapper"> <div class="container-fluid"> <!-- /.row --> <div class="row"> <!--div class="col-md-8 col-md-offset-4"--> <div class="col-lg-6"> <div class="Register-panel panel panel-default"> <!--div class="panel panel-default"--> <div class="panel-heading"> Edit Item </div> <div class="panel-body"> <div class="row"> <div class="col-lg-6"> <div class="panel-body"> <form role="form" action=""> <input type="text" name="item_id" value=<?php echo $item_id; ?> readonly><br> <input type="text" name="item_name" required autofocus placeholder="Item-Name" value=<?php echo $item_name; ?>><br> <input type="text" name="description" required autofocus placeholder="Description" value=<?php echo $description; ?>><br> <input type="text" name="item_category" required autofocus placeholder="Item_category" value=<?php echo $item_category; ?>><br> <input type="text" name="pic" required autofocus placeholder="pic" value=<?php echo $pic; ?>><br> <input type="submit" name="updateitemBtn" value="Update"> </form> </div> </div> <!-- /.col-lg-6 (nested) --> </div> <!-- /.row (nested) --> </div> <!-- /.panel-body --> </div> <!-- /.panel --> </div> <!-- /.col-lg-12 --> </div> <!-- /.row --> </div> <!-- /.container-fluid --> </div> <!-- /#page-wrapper -->
